2013 ERCB Annual Pressure Requirements
The ERCB has published the 2013 list of Annual Pressure Requirements. Don’t forget that surface data and acoustic well sounder (AWS) surveys are acceptable for compliance. Since we have a whole year it is a good idea to coordinate testing with a plant turnaround, a pump change, or a routine maintenance shut-in. Testing water or gas injection wells is another good tactic for sustaining oil revenues. What’s not specifically clear in G40 is that Pressure Transient Analysis (PTA) is acceptable for estimating Annual Pressure Oil and Annual...

Characterizing Reservoir Properties using Diagnostic Fracture Injection Testing (DFIT) was presented at a recent Society of Petroleum Engineers (SPE) luncheon. A great talk – and a great reservoir diagnostic test – as our example Level 2 eREPORT illustrates: DFIT2 Mini-frac’ Fall-off. But…here in Alberta…as per ERCB Bulletin 2010-38 surface (or acoustic well sounder) data are no longer acceptable for Initial Pressure Gas or Initial Pressure Oil requirements. For compliance with Initial Pressure requirements the...
